<p><code>Go Module</code> 是官方用来管理 <code>package</code> 依赖的工具, <code>1.11</code> 新加的, 使用时需要设置变量: <code>GO111MODULE=on</code> .</p>
<p><code>go mod help</code> 可以查看其帮助文档:</p>
<div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-shell" data-lang="shell"><span style="display:flex;"><span>$ go help mod
</span></span><span style="display:flex;"><span>Go mod provides access to operations on modules.
</span></span><span style="display:flex;"><span>
</span></span><span style="display:flex;"><span>Note that support <span style="color:#66d9ef">for</span> modules is built into all the go commands,
</span></span><span style="display:flex;"><span>not just <span style="color:#e6db74">&#39;go mod&#39;</span>. For example, day-to-day adding, removing, upgrading,
</span></span><span style="display:flex;"><span>and downgrading of dependencies should be <span style="color:#66d9ef">done</span> using <span style="color:#e6db74">&#39;go get&#39;</span>.
</span></span><span style="display:flex;"><span>See <span style="color:#e6db74">&#39;go help modules&#39;</span> <span style="color:#66d9ef">for</span> an overview of module functionality.
</span></span><span style="display:flex;"><span>
</span></span><span style="display:flex;"><span>Usage:
</span></span><span style="display:flex;"><span>
</span></span><span style="display:flex;"><span>        go mod &lt;command&gt; <span style="color:#f92672">[</span>arguments<span style="color:#f92672">]</span>
</span></span><span style="display:flex;"><span>
</span></span><span style="display:flex;"><span>The commands are:
</span></span><span style="display:flex;"><span>
</span></span><span style="display:flex;"><span>        download    download modules to local cache
</span></span><span style="display:flex;"><span>        edit        edit go.mod from tools or scripts
</span></span><span style="display:flex;"><span>        graph       print module requirement graph
</span></span><span style="display:flex;"><span>        init        initialize new module in current directory
</span></span><span style="display:flex;"><span>        tidy        add missing and remove unused modules
</span></span><span style="display:flex;"><span>        vendor      make vendored copy of dependencies
</span></span><span style="display:flex;"><span>        verify      verify dependencies have expected content
</span></span><span style="display:flex;"><span>        why         explain why packages or modules are needed
</span></span><span style="display:flex;"><span>
</span></span><span style="display:flex;"><span>Use <span style="color:#e6db74">&#34;go help mod &lt;command&gt;&#34;</span> <span style="color:#66d9ef">for</span> more information about a command.
</span></span></code></pre></div><p>下面来说明下如何使用.</p>
<hr>
<h3 id="示例">示例</h3>
<p><code>go mod</code> 要求项目必须在 <code>GOPATH</code> 中, 所以在这个例子中设置为当前目录(<code>~/GoLang</code>) <code>export GOPATH=$PWD</code>, 然后在 <code>src</code> 下创建项目 <code>test</code> , 目录结构如下:</p>
<div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-shell" data-lang="shell"><span style="display:flex;"><span>GoLang
</span></span><span style="display:flex;"><span>└── src
</span></span><span style="display:flex;"><span>    └── test
</span></span><span style="display:flex;"><span>        └── main.go
</span></span></code></pre></div><p>示例的代码请见: <a href="https://github.com/jouyouyun/examples/tree/master/GoModule">GoModule</a></p>
<h4 id="初始化">初始化</h4>
<p>进入 <code>test</code> 所在目录, 执行 <code>go mod init</code> 即可完成初始化, 会多出一个文件: <code>go.mod</code> .</p>
<h4 id="记录依赖">记录依赖</h4>
<p>执行 <code>go get ./</code> 即会开始查找依赖并下载记录到 <code>go.mod</code> 文件中.</p>
<p><strong><code>go mod</code> 会将依赖下载到 <code>$GOPATH/pkg</code> 下, 用来当作缓存, 可以在多个项目之间共享.</strong></p>
<h4 id="依赖变更及-vendor">依赖变更及 vendor</h4>
<p>如在项目的开发过程中, 依赖有变更, 可使用 <code>go mod tidy</code> 来应用这些变更到 <code>go.mod</code> 文件.</p>
<p>在项目发布时会要将依赖复制到项目中, 此时使用 <code>go mod vendor</code> 即可完成此操作.</p>
<hr>
<p>到此就介绍完了 <code>go mod</code> 的用法, 其他的子命令用法请查看帮助文档.</p>
<p>最后在说下需要注意的地方:</p>
<ol>
<li><strong>项目必须要在 <code>GOPATH</code> 中</strong></li>
<li><strong>需要设置 <code>GO111MODULE=on</code> 变量</strong></li>
